PIANO-SEAT ATTACHMENT.

Specification of Letters Patent.

Patented May 14:, 1918.

Application filed April 21, 1917. serial No. 163,655.

To all whom it may concern Be it known that I,MARTIN GosANELLI, a citizen of the United States, residing at Woodside, in the county of Queens and State of New York, have invented certain new and useful Improvements in Piano-Seat Attachments, of which the following is a specification.

This invention relates to new and useful improvements in stools and more particularly in a piano stool.

The primary object of the invention is to provide a stool which may be movably supported beneath a table, or more specifically the key board of a piano or other musical instrument and is adjustable to a position beneath said key board so as to be out of the way when not in use.

Another object is to provide asupporting post which is adapted to be slidably and r0- tatably secured to the underside of a key board and is equipped with an adjustable seat.

A further object isto provide a novel supporting means for attaching a stool to the key board of a musical instrument.

These and other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description and accompanying drawings.

In the drawings:

Figure 1 is a side view showing the application of my improved stool.

Fig. 2 is a top plan view and Fig. 3 is an end View with parts taken away.

The preferred embodiment of my invention includes a plate 1 which is preferably of an oblong configuration and is adapted to be secured to the underface of the keyboard of a piano or other musical instrument as clearly shown in Figs. 1 and 2 of the drawings. The plate 1 is dropped or is otherwise formed intermediate its lateral margins to provide a casing 2, open at one end and equipped with a longitudinal slot 3. A plate a is provided, which when the parts are assembled, closes the open end of the casing 2. The numeral 5 indicates a vertical supporting post which has its lower end bent to provide a laterally extending arm 6, the latter being equipped with the upturned end 7 A seat 8 is shown and has its depending threaded shank or pedestal 9 adjustably engaged in a threaded bore formed in the upturned end 7 of the arm 6; The upper end of thepost 5 is slidably mounted in the slot 8 and terminates in an enlarged rounded head 10 which is supported in the casing 2 as shown. The head 10 is of a thickness corresponding to the depth of the casing so as to prevent undue vertical movement of the post 5, and the head is made round so that it and the post may rotate on their common axis. To give further rigidity to the post 5 I have provided thereon an enlarged bearing plate 11 which is spaced a suitable distance from the head 10 to frictionally engage the lower face of the casing 2. The enlarged bearing plate prevents lateral movement of the post 5 and is adapted to take up the strain exerted on said post when the seat 8 is occupied. As clearly shown, the plate 11 is segmental in shape and is eccentrically disposed on the post 5, being rigidly supported thereon by means of a brace 12 with its major portion on that side of the post opposite the arm 6.

In assembling, the plate 1 carrying the casing 2 is secured to the underside of the keyboard, and the head of post 5 is inserted in the casing from the open end thereof. The plate 4: is then secured to the open end of the casing to retain the parts in position. From the foregoing, it will be seen that the supporting post 5 carrying the stool seat 8 is both slidably and rotatably mounted in the casing 2 so that the seat when not in use, may be turned aside or slid to a position beneath the keyboard.

Although I have described my device as attached to a keyboard, it is not limited to this application but may be attached to a store counter or any other suitable supporting object; and I furthermore reserve the right to make such changes in construction and arrangement of parts as may come within the scope of the appended claims without departing from the spirit of the invention.

What I claim is:

1. In a seat attachment, the combination with a slotted supporting plate adapted to be mounted beneath a table; of a post having its upper end slidably and rotatably mounted in said slot and provided with enlargements spaced to make simultaneous contact with the upper and lower faces of said plate, and a seat carried by and laterally offset from said post.

2. In a piano seat attachment, the combination with a plate adapted to be secured to the lower side of the key board and provided with a dropped casing having a longitudinal slot; of a post having at its lower end a lateral arm carrying a seat, a round head at its upper end slidably and rotatably mounted Within said casing and of a greater diameter than the Width of said slot, a bearing plate rigidly secured to the post beneath its head and sliding in contact with the lower face of said casing when the post is adjusted, said plate being of segmental formation with its major area on that side of the post opposite said arm, and a brace connecting the post with this plate at the point of its longest radius.

In testimony whereof I affix my signature in presence of two Witnesses.
